1. The Old Man from the Countryside Becomes a Sword Saint
Beryl Gardinant is a middle-aged swordmaster who runs a humble dojo in the countryside, fully accepting that his dreams of reaching the pinnacle of swordsmanship are behind him. His quiet life is abruptly turned upside down when his former student, Aliusia—who has since risen to the prestigious rank of Kingdom Knight Commander—arrives after ten years. She appoints him as a special instructor for the knights, forcing Beryl to leave his peaceful rural life for the bustling capital, where he reunites with immensely powerful former students and faces formidable new foes.
This series is a breath of fresh air in a medium often dominated by overpowered teenage protagonists. Beryl’s humility and severe imposter syndrome, contrasted with his genuinely terrifying sword skills, make him an incredibly endearing lead. It appeals perfectly to older anime fans and anyone tired of standard tropes, offering wholesome mentorship and spectacular action. With its growing popularity, fans are already looking forward to how the franchise will expand, especially with Season 2 of the series set to air starting in July.
2. The Apothecary Diaries Season 2
Following the revelation of the Emperor’s favorite concubine Gyokuyou’s pregnancy, Maomao returns to the Jade Pavilion to resume her role as a poison taster. Her days are spent on high alert to prevent any further attempts on the lives of the concubine and the royal child. However, the palace is brewing with unprecedented turmoil—including the arrival of a new consort with powerful political ties, an assassination attempt on Jinshi, and the looming presence of mysterious foreign envoys making unreasonable demands.
The Apothecary Diaries continues to be a monumental success, blending intricate historical mysteries with subtle, slow-burn romance. Maomao remains one of the most uniquely pragmatic and brilliant female protagonists in modern anime. This sequel promises to elevate the stakes, shifting from isolated palace incidents to grand political conspiracies that threaten the entire nation. It is an absolute must-watch for fans of drama and meticulous world-building.
3. The Perfect but Unlovable Saint Gets Sold to a Neighboring Country
In the kingdom of Jiltonia, Philia is hailed as the greatest Saint in history, tirelessly protecting the nation from monsters thanks to her strict upbringing. However, her flawless efficiency makes her appear emotionless, leading her fiancé, the Second Prince Julius, to abruptly cancel their engagement for her lack of “charm.” To make matters worse, she is practically sold off to the neighboring Palnacorta Kingdom in exchange for resources. Expecting a life of misery, Philia is shocked to find a kingdom that welcomes her with open arms and overwhelming gratitude.
This series caters perfectly to fans of the increasingly popular villainess and redemption genres. It is immensely satisfying to watch an underappreciated, overly competent heroine finally receive the love and respect she deserves while her former kingdom slowly realizes the catastrophic mistake they made. If you enjoy stories about personal healing and sweet revenge, this is an excellent addition to the top villainess anime you can’t miss.
4. I’m the Evil Lord of an Intergalactic Empire!
Liam is a reincarnated soul who takes over as the head of a ruling family in the sprawling, sci-fi Algrand Empire. Having lived a tragically miserable past life because he was too kind and constantly taken advantage of, he vows to live out this new life as a tyrannical “evil lord.” He plans to build a harem, pilot giant mechas, and squeeze his subjects dry. There is just one massive problem: every selfish, supposedly evil action he takes accidentally improves the lives of his citizens, causing them to worship him as a benevolent genius.
Merging classic isekai mechanics with a vibrant sci-fi and mecha setting, this comedy thrives on sheer misunderstanding. The dramatic irony of Liam trying his hardest to be a villain while inadvertently creating a utopian society never gets old. It is hilarious, action-packed, and perfectly paces its grand galactic world-building with side-splitting character interactions.
5. The Genius Healer Who Was Exiled as “Useless” After Healing Instantly Lives Happily as a Dark Healer
Zenos is a highly skilled but unlicensed healer born in the slums who uses his own unique brand of magic. Because his healing is instantaneous, his adventurer party assumes he is doing nothing and abruptly kicks him out with a single gold coin as severance. Unemployed and wandering the back alleys, Zenos encounters a dying elf girl named Lily. After effortlessly saving her life, he decides to open a secret underground clinic in the ruins, operating as a “dark healer” who cures the uncurable and punishes the corrupt.
The “exiled from the hero’s party” trope is executed brilliantly here by focusing on the medical and underground aspects of a fantasy world. Zenos is a compelling anti-hero who ignores the bureaucracy of the magical world to do what is right on his own terms. The found-family dynamic he builds with Lily and his eccentric patients gives the show a surprisingly warm heart amidst its darker themes.
6. The Misunderstood Atelier Owner: The Former Chore Boy of the Hero’s Party Was Actually SSS Rank in Everything Except Combat
Kurt is a kind-hearted boy who serves as the chore worker for a renowned hero’s party until he is suddenly fired for being “useless in battle.” Forced to find a new way to make a living, he starts taking on odd jobs around town. To everyone’s shock, Kurt possesses literal god-tier abilities in crafting, cooking, and building—he is SSS rank in every non-combat skill imaginable. Kurt, however, is completely oblivious to his own overpowered nature, believing his miraculous feats are just “normal everyday tasks.”
This slice-of-life fantasy is pure comfort food. The humor stems entirely from Kurt accidentally saving towns, shifting national economies, and solving impossible crises simply by doing his daily chores. It is a relaxing, feel-good anime that proves you do not need to swing a sword to be the most important person in a fantasy realm.
7. Can a Boy-Girl Friendship Hold Up? (No, It Can’t!!)
Himari Inuzuka, a cheerful extrovert, and Yuu Natsume, a quiet plant-loving boy, swore eternal friendship to one another in middle school. Now in their second year of high school, they are the sole members of the gardening club, maintaining a perfectly peaceful and strictly platonic relationship. However, the delicate balance of their friendship is shattered when Yuu unexpectedly reunites with his first love from the past. Suddenly, Himari is forced to confront feelings she never knew she had.
Diving deep into the classic debate of whether men and women can truly just be friends, this series offers a highly relatable and emotionally charged narrative. The character chemistry is palpable, and the shifting dynamics capture the messy, confusing nature of teenage romance.

8. Once Upon a Witch’s Death
On her 17th birthday, apprentice witch Meg Raspberry is given a devastating prophecy by her master, Faust: she only has one year left to live due to a deadly curse. Her only hope for survival is to create the “Seed of Life,” a legendary artifact that grants immortality. The catch? The primary ingredient requires collecting the tears of joy from one thousand different people. Thus begins Meg’s emotional journey to bring happiness to the lives of strangers, friends, and powerful fellow witches before her time runs out.
Visually stunning and emotionally profound, this anime is poised to be the tear-jerker of the year. Meg’s quest is less about magical battles and more about human connection, empathy, and understanding the weight of mortality. It is a beautiful, melancholic, yet ultimately uplifting tale that will leave a lasting impact on viewers.
9. Our Last Crusade or the Rise of a New World Season 2
The highly advanced mechanical utopia known as the Empire and the magically gifted Nebulis Sovereignty have been locked in a brutal war for generations. Iska, the Empire’s strongest swordsman, and Alice, the Sovereignty’s revered “Ice Calamity Witch,” previously clashed on the battlefield only to realize they share the same dream of peace. Now, under the guise of an undercover mission, Iska infiltrates the Sovereignty as a bodyguard for Alice’s sister, leading to a fateful and dangerous reunion between the star-crossed enemies as internal conspiracies threaten to destroy both nations.
Returning with higher stakes and breathtaking animation, this sequel beautifully expands upon its “Romeo and Juliet” premise. The blend of high-tech weaponry clashing against overwhelming magical forces creates some of the most visually spectacular battles in recent memory. The political intrigue and genuine romance make it an unforgettable fantasy epic.
10. I May Be a Guild Receptionist, but I’ll Solo Any Boss to Clock Out on Time
Alina Clover took a job as a guild receptionist because she wanted a safe, stable public service career where she could do her paperwork and go home exactly on time. Unfortunately, incompetent adventurers constantly stall in dungeons, causing massive backlogs of paperwork and forcing Alina into endless, agonizing overtime. Having finally reached her breaking point, she decides to take matters into her own hands. Wielding a massive silver warhammer, she secretly moonlights as an anonymous executioner, solo-killing raid bosses just so she can clock out and go to bed.
Winner of the prestigious Dengeki Novel Prize, this anime is a hilarious love letter to anyone who has ever suffered through corporate burnout. Alina’s rage-fueled rampages are intensely satisfying and gorgeously animated. The constant suspense of her trying to keep her overpowered double-life a secret from her coworkers makes for a brilliantly entertaining watch.
